Tsikhon Kuprevich closed RF-1341. --------------------------------- > Problems with Ajax requests within a a4j:repeat loop > ---------------------------------------------------- > > Key: RF-1341 > URL: http://jira.jboss.com/jira/browse/RF-1341 > Project: RichFaces > Issue Type: Bug > Affects Versions: 3.1.3 > Environment: MyFaces, Richfaces 3.1.3 snapshot > Reporter: Peter Mahoney > Assigned To: Alexander Smirnov > Fix For: 3.2.0, 3.2.1 > > > I have come across two problems following a change to put some fields in an > a4j:repeat loop. The backing beans have not changed. This is the code: > <a4j:repeat id="termClauses" > value="#{collectionSearchHandler.termClauses}" var="clause"> > <a4j:region > id="vocabularyFilterRegion"> > > <h:selectOneMenu id="vocabularyFilter" value="#{clause.vocabulary}"> > > <a4j:support id="vocabularyAjaxSupport" event="onchange" > reRender="termFilterPanel" ajaxSingle="true" /> > > <f:selectItem itemValue="#{collectionSearchHandler.blankVocabulary}" > itemLabel="#{msgs.quizFirstVocabularySelectItemDescription}" /> > > <f:selectItems value="#{collectionSearchHandler.vocabularyFilterItems}" /> > > </h:selectOneMenu> > <a4j:status > startText="#{msgs.quizTermSearchInProgressMessage}" /> > </a4j:region> > <a4j:region > id="termFilterRegion"> > > <a4j:outputPanel id="termFilterPanel"> > > <h:panelGroup rendered="#{clause.hasVocabulary}"> > > <ul style="list-style-type:none; margin:0px;"> > > <a4j:repeat id="termFilters" value="#{clause.termFilters}" > var="termFilter" rowKeyVar="idx"> > > <li> > > <h:selectOneMenu id="termFilter" > value="#{termFilter.term}" converter="com.dbplc.quiz.Term" style="width:100%"> > > <a4j:support id="termAjaxSupport" > event="onchange" reRender="termFilterPanel,qbankSearchResultsPanel" > ajaxSingle="true" actionListener="#{collectionSearchHandler.searchPerformed}" > /> > > <f:selectItem > itemValue="#{collectionSearchHandler.blankTerm}" > itemLabel="#{msgs.quizFirstTermSelectItemDescription}" /> > > <f:selectItems > value="#{clause.termFilterItemMap[idx]}" /> > > </h:selectOneMenu> > > <h:commandButton > actionListener="#{collectionSearchHandler.searchPerformed}" /> > > </li> > > </a4j:repeat> > > </ul> > > </h:panelGroup> > > </a4j:outputPanel> > <rich:messages > /> > </a4j:region> > </a4j:repeat> > Firstly I get the following error when the form is submitted by changing the > "VocabularyFilter" value: > /questionsearch.xhtml @25,77 value="#{clause.vocabulary}": Target > Unreachable, identifier 'clause' resolved to null > If I add an onchange="this.form.submit()" to the field, to bypass the Ajax, > it works fine. > So, with the above workaround, I then get the problem that the > collectionSearchHandler.searchPerformed() method (referenced by the > a4j:support tag) is only called every second form submit. This worked without > problems before adding the outer a4j:repeat. Using the commandButton to > submit the form works every time. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira _______________________________________________ richfaces-issues mailing list [email protected] https://lists.jboss.org/mailman/listinfo/richfaces-issues
